At some level, the Humean doubts about the illogic of induction have to give way, and you make assumptions you cannot justify. If you listen to talk radio, everyone has a really strong opinion, but it gets you thinking, sets up an argument to critique. We make decisions based on assumptions and theories, and these are all suspect, but I think without some decisiveness that could be called overconfidence, we would be catatonic.

btw: do they even have Goofus and Gallant any more? I would think highlighting evil Goofus would be blaming the victim.
